Struts2.3接收post方式提交的表单参数的方式

一：方式一：通过request来获取，首先让action实现ServletRequestAware接口，然后通过request来获取提交的参数，代码如下:

package cn.gov.csrc.flight.action;
    
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    
    import org.apache.struts2.convention.annotation.Action;
    import org.apache.struts2.convention.annotation.ParentPackage;
    import org.apache.struts2.convention.annotation.Result;
    import org.apache.struts2.interceptor.ServletRequestAware;
    import org.apache.struts2.json.annotations.JSON;
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    
    import cn.gov.csrc.base.action.BaseAction;
    import cn.gov.csrc.cms.model.UserInfo;
    import cn.gov.csrc.cms.service.UserService;
    import cn.gov.csrc.flight.model.Flgtinfo_D;
    import cn.gov.csrc.flight.service.FlgtinfodService;
    
    @Controller
    @ParentPackage("json-default") 
    @Scope("prototype")
    public class FlgtinfodAction extends BaseAction<Flgtinfo_D> implements ServletRequestAware{
    	
    	private static final long serialVersionUID = 1L;
    	
    	private FlgtinfodService flgtinfodService;
    	
    	private Map<String, Object> dataMap;
    	
    	HttpServletRequest request;
    	
    	public FlgtinfodAction(){
    		dataMap = new HashMap<String, Object>();
    	}
    	
    	@Resource
    	public void setFlgtinfodService(FlgtinfodService flgtinfodService) {
    		this.flgtinfodService = flgtinfodService;
    	}
    	
    	@Action(value = "FlgtinfodAction_detail", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })
    	public String detail(){
    		dataMap.clear(); 
    		//查询出港详情(根据用户id，列表到详情的唯一编号)
    		String id = this.request.getParameter("id");
    		Flgtinfo_D flgtinfo_D = flgtinfodService.getEntity(id);
    		String airline2 = flgtinfo_D.getAirline();
    		// 出港详情放入到dataMap中
    		dataMap.put("flgtinfo_D", flgtinfo_D);
    		// 放入一个是否操作成功的标识 
    		dataMap.put("success", true);
    		return "success";
    	}
    
    	public Map<String, Object> getDataMap() {
    		return dataMap;
    	}
    	
    	@Override
    	public void setServletRequest(HttpServletRequest request) {
    		this.request = request;
    	}
    	
    }

二：方式二，直接在action里面写你要提交的参数，然后提供set，get方法，代码如下：

package cn.gov.csrc.flight.action;
    
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    
    import org.apache.struts2.convention.annotation.Action;
    import org.apache.struts2.convention.annotation.ParentPackage;
    import org.apache.struts2.convention.annotation.Result;
    import org.apache.struts2.interceptor.ServletRequestAware;
    import org.apache.struts2.json.annotations.JSON;
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    
    import cn.gov.csrc.base.action.BaseAction;
    import cn.gov.csrc.cms.model.UserInfo;
    import cn.gov.csrc.cms.service.UserService;
    import cn.gov.csrc.flight.model.Flgtinfo_D;
    import cn.gov.csrc.flight.service.FlgtinfodService;
    
    @Controller
    @ParentPackage("json-default") 
    @Scope("prototype")
    public class FlgtinfodAction extends BaseAction<Flgtinfo_D>{
    	
    	private static final long serialVersionUID = 1L;
    	
    	private Integer id; // 列表到详情的唯一标识
    	
    	private FlgtinfodService flgtinfodService;
    	
    	private Map<String, Object> dataMap;
    	
    	public FlgtinfodAction(){
    		dataMap = new HashMap<String, Object>();
    	}
    	
    	@Resource
    	public void setFlgtinfodService(FlgtinfodService flgtinfodService) {
    		this.flgtinfodService = flgtinfodService;
    	}
    	
    	@Action(value = "FlgtinfodAction_find", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })
    	public String find() {
            dataMap.clear(); 
    		//查询出港信息
    		List<Flgtinfo_D> list = flgtinfodService.findAllFlgtinFods();
    		// 出港信息放入到dataMap中
    		dataMap.put("list", list);
    		// 放入一个是否操作成功的标识 
    		dataMap.put("success", true);
    		return "success";
    	}
    	
    	@Action(value = "FlgtinfodAction_detail", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })
    	public String detail(){
    		dataMap.clear(); 
    		//查询出港详情(根据用户id，列表到详情的唯一编号)
    		id = model.getId();
    		Flgtinfo_D flgtinfo_D = flgtinfodService.getEntity(id);
    		String airline2 = flgtinfo_D.getAirline();
    		// 出港详情放入到dataMap中
        		dataMap.put("flgtinfo_D", flgtinfo_D);
        		// 放入一个是否操作成功的标识 
        		dataMap.put("success", true);
    		return "success";
    	}
    
    	public Integer getId() {
    		return id;
    	}
    
    	public void setId(Integer id) {
    		this.id = id;
    	}
    
    	public Map<String, Object> getDataMap() {
    		return dataMap;
    	}
    	
    	
    }
